Description

Technical Field

[0001] The present invention relates to the technical field of automotive heat dissipation, and particularly to an efficient cooling water circulation system for an automotive radiator. Background Art

[0002] As an important part of the engine cooling system, the main function of an automotive radiator is to effectively dissipate the heat generated during the operation of the engine into the environment to keep the engine temperature within the normal operating range. Automotive radiators are generally divided into water-cooled and air-cooled types. In water-cooled heat dissipation, the radiator in the water tank is responsible for cooling the coolant with the high temperature of the engine, and at the same time, the coolant circulates in the entire cooling system. In air-cooled heat dissipation, the high-temperature coolant in the radiator is cooled by directly blowing the ambient temperature towards the radiator through the operation of a fan.

[0003] In the prior art, the inlet water tank and the outlet water tank on the automotive radiator are welded by a rectangular plate and a trapezoidal frame, and the automotive radiator is generally rigidly fixed on the vehicle by bolts. Whenever the vehicle is driving, it will generate bumps and vibrations. Since the acting force generated by the vibration will directly act on the inlet water tank and the outlet water tank on the radiator, cracks will be caused at the welded joints. Long-term vibration will cause the cracks to increase and rupture, resulting in water leakage, further affecting the normal operation of the cooling system.

[0004] In addition, the inlet pipe and the outlet pipe are also fixed to the trapezoidal frame of the inlet water tank and the outlet water tank by welding. Similarly, vibration will cause the cracks at the welded joints to increase and rupture, resulting in water leakage. Summary of the Invention

[0029] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art can think of other obvious variations.

[0030] As Figures 1-8 shown, an efficient cooling water circulation system for an automotive radiator includes a radiator body. The radiator body includes an inlet water tank 12 and an outlet water tank 7. At the mutually remote ends of the inlet water tank 12 and the outlet water tank 7, an inlet pipe 16 and an outlet pipe 3 are fixedly connected respectively. A reinforcement mechanism, a limit mechanism, a buffer mechanism, and a cleaning mechanism are provided on the inlet water tank 12, the outlet water tank 7, the inlet pipe 16, and the outlet pipe 3;

[0031] AsFigure 1 , Figure 2 As shown in Figure 2 , the reinforcement mechanism includes reinforcement plates 6 arranged on the inclined surfaces of the water inlet tank 12 and the water outlet tank 7. At one end where the two groups of reinforcement plates 6 are close to each other, an inner tension rope 13 and an outer tension rope 14 are symmetrically and fixedly connected respectively. The outer tension rope 14 is arranged outside the inner tension rope 13 and they are cross - arranged with each other. The other ends of the two groups of inner tension ropes 13 and outer tension ropes 14 are fixedly connected with a first tension ring 5 and a second tension ring 15 respectively. A first reinforcement rope 1 is fixedly connected between the first tension ring 5 and the second tension ring 15 and the reinforcement plates 6. The first tension ring 5 and the second tension ring 15 move towards both sides to make the first reinforcement rope 1, the inner tension rope 13 and the outer tension rope 14 in a tensioned state, and reinforce the water inlet tank 12 and the water outlet tank 7; the limiting mechanism is used to limit the first tension ring 5 and the second tension ring 15 to prevent loosening during use.

[0032] As Figure 4 , Figure 5 As shown in Figure 5 , the limiting mechanism includes rotating rings 23 rotatably connected to the inner walls of the first tension ring 5 and the second tension ring 15. A plurality of uniformly arranged card slots 22 are opened on the outer walls of the two rotating rings 23 corresponding to the outside of the first tension ring 5 and the second tension ring 15. Fixing plates 24 are fixedly connected to the four sides of the first tension ring 5 and the second tension ring 15 away from each other. A clamping post 19 slides through each fixing plate 24, and each clamping post 19 is provided with an inclined surface, and each clamping post 19 is stuck in the fixing plate 24. When the rotating ring 23 rotates, the card slots 22 rotate synchronously and contact the inclined surface of the clamping post 19, so that the clamping post 19 can move outward until the clamping post 19 is stuck in a suitable card slot 22 to complete the limitation of the rotating ring 23.

[0033] As Figure 4 , Figure 5 As shown in Figure 5 , the limiting mechanism further includes a limiting frame 20 fixedly connected to the inner side of the outer wall of each clamping post 19. A first spring 18 is fixedly connected between each group of limiting frames 20 and the clamping post 19. External threads 17 are fixedly connected to the outer walls of the water inlet tank 12 and the water outlet pipe 3. Thread grooves adapted to the shape of the external threads 17 are opened on the inner walls of the two rotating rings 23. Through the cooperation of the thread grooves and the external threads 17, the rotating rings 23 can move while rotating, so that the first reinforcement rope 1, the inner tension rope 13 and the outer tension rope 14 can be tensioned and reinforced.

[0034] As Figure 3 , Figure 5As shown in the figure, the limiting mechanism further includes annular grooves 28 formed at the mutually remote ends of the first tensioning ring 5 and the second tensioning ring 15. Limiting rings 2 are provided on the inner walls of the two annular grooves 28. A plurality of telescopic columns 25 are fixedly connected to the mutually close ends of the two limiting rings 2. Each telescopic column 25 respectively penetrates through the first tensioning ring 5 and the second tensioning ring 15. A circular plate 27 is fixedly connected to the other end of each telescopic column 25. A first tension spring 26 is fixedly connected between each circular plate 27 and the first tensioning ring 5 and the second tensioning ring 15. When reinforcement is carried out, the limiting ring 2 is first received into the annular groove 28. At this time, the first tension spring 26 is in a stretched state. When the limiting ring 2 is released, the reset movement of the first tension spring 26 can make the limiting ring 2 extend out of the annular groove 28, and the limiting ring 2 is used to limit the clamping column 19.

[0035] As Figure 4 shown, guide rods 21 are fixedly connected to the outer sides of the water inlet pipe 16 and the water outlet pipe 3 corresponding to the mutually remote ends of the water inlet tank 12 and the water outlet tank 7. The two groups of guide rods 21 respectively penetrate through the first tensioning ring 5 and the second tensioning ring 15. The number of each group of guide rods 21 is set to four and is symmetrically distributed about the center lines of the water inlet pipe 16 and the water outlet pipe 3. The provided guide rods 21 can limit the first tensioning ring 5 and the second tensioning ring 15 to prevent deflection.

[0036] As Figure 2 、 Figure 4 shown, the buffer mechanism includes mounting frames 4. Two circular columns 29 are slidably penetrated through the upper and lower ends of the two mounting frames 4. Each group of circular columns 29 is fixedly connected to the water inlet tank 12 and the water outlet tank 7. A limiting disk 9 is fixedly connected to the mutually remote end of each group of circular columns 29. An elastic member 8 is fixedly connected between each limiting disk 9 and the mounting frame 4. Elastic members 8 are fixedly connected between the water inlet tank 12 and the water outlet tank 7 and the mounting frame 4. The elastic member 8 can be a spring or a tension spring. The elastic member 8 can cancel the vibration force generated during the driving of the vehicle, and the vehicle radiator is installed at a suitable position on the vehicle through the mounting frame 4.

[0037] As Figure 7 、 Figure 8As shown, the cleaning mechanism includes vertical rods 30 fixedly connected to the upper and lower sides of the inner wall of the mounting frame 4, two groups of vertical rods 30 slide through the water inlet tank 12 and the water outlet tank 7, a rack 31 is fixedly connected between the two groups of vertical rods 30, a plurality of heat dissipation pipes 36 and two connecting plates 10 are fixedly connected between the water inlet tank 12 and the water outlet tank 7, a plurality of heat dissipation fins 11 are fixedly connected between the heat dissipation pipes 36 and the connecting plates 10, and a fixing frame 35 is fixedly connected to the outer sides of the heat dissipation pipes 36 corresponding to the inner walls of the water inlet tank 12 and the water outlet tank 7, and each group of fixing frames 35 is rotatably connected with a rotating shaft 34, and scrapers 33 are fixedly connected on both sides of the outer wall of each rotating shaft 34, and a gap is left between each group of scrapers 33 and each heat dissipation pipe 36, and each end of each rotating shaft 34 is fixedly connected with a gear 32, and each group of gears 32 is meshed with two racks 31 respectively. When the car radiator moves up and down, the gear 32 moves along the tooth surface on the rack 31, thereby rotating the gear 32, and then rotating the shaft 34 and the scraper 33. Therefore, when scale is formed on the inner wall of the heat pipe 36, it can be scraped off to ensure the heat dissipation effect of the heat pipe 36.

[0038] Working principle: First, the limiting ring 2 is stored in the annular groove 28 to release the limit on the clamping column 19, and then the rotating rings 23 on both sides are rotated. Due to the threaded groove on the inner wall of the rotating ring 23 and the thread effect of the external thread 17, the rotating ring 23 can be moved to both sides, and the rotating rings 23 on both sides respectively carry the first tensioning ring 5 and the second tensioning ring 15 on both sides to move. During movement, the guide rod 21 can play a guiding and limiting role to prevent the deviation and instability during the movement. At this time, the first reinforcement rope 1, the inner tensioning rope 13 and the outer tensioning rope 14 are tightened to the reinforcement plate 6 on the inclined surface of the water inlet tank 12 and the water outlet tank 7. Since the first reinforcement rope 1, the inner tensioning rope 13 and the outer tensioning rope 14 are made of metal, they have high tensile strength. Therefore, after tightening, the water inlet tank 12 and the water outlet tank 7 can be reinforced to prevent cracks in the welds on the water inlet tank 12 and the water outlet tank 7 during use, avoid water leakage, and prevent affecting the use of the cooling system;

[0039] When the rotating ring 23 rotates, the slot 22 will first contact the inclined surface on the post 19, which will squeeze the post 19 to move outward. At the same time, the limiting frame 20 will squeeze the first spring 18 until the post 19 is stuck in the appropriate slot 22, completing the limit of the rotating ring 23. At this time, the limiting ring 2 is released and the elastic reset action of the first tension spring 26 can reset the circular plate 27 and the telescopic column 25, so that the limiting ring 2 can leave the range of the annular groove 28 and make the inner wall of the limiting ring 2 contact the outer end of the post 19. Therefore, the post 19 can be limited to prevent the post 19 from leaving the range of the slot 22 during driving, thereby ensuring the reinforcement effect.

[0040] In addition, during the driving process of the vehicle, the elastic member 8 can buffer the vibration generated by bumps, preventing the vibration force from directly acting on the vehicle radiator. Therefore, the welds on the vehicle radiator can be further protected. When the vehicle radiator moves up and down, since the gear 32 is meshed with the rack 31, the gear 32 will move along the tooth surface of the rack 31 and rotate simultaneously. The gear 32 drives the rotating shaft 34 and the scraper 33 to rotate. When scale appears on the inner wall of the heat dissipation pipe 36, the scraper 33 can clean up the generated scale and ensure the heat dissipation effect of the heat dissipation pipe 36.

Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification is only the principle of the present invention.
